Please clarify the braced and un-braced design conditions

These are design principles chosen by structural engineer for design of buildings. These are beyond purview of RCDC. RCDC captures this as information for further calculations.

As per clause 39.7.1 (Notes), IS code allows user to design column based on Braced and Un-braced conditions. The end moments are calculated based on end conditions given in this clause.

In Euro code, the braced and Unbraced option is available for calculation of effective length factor.
